Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favour convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per...

The controversy over the appropriate partitioning of East Asian growth into accumulation versus technical change has overlooked a fundamental indeterminacy in measurement. As a result, we cannot rule out the possibility that East Asia has in fact experienced a tremendous amount of technological...

Convergence in per capita income across countries turns on whether technological knowledge spillovers are global or local in a large class of models. This Paper estimates the amount of spillovers from R&D expenditures in major industrialized countries on a geographic basis. A new data set is...

We construct a revised version of the Barro and Lee (1996) data set for a sample of OECD countries using previously unexploited sources and following a heuristic approach to obtain plausible time profiles for attainment levels by removing sharp breaks in the data that seem to reflect changes in...

We investigate the sources of productivity convergence using panel data for the Spanish regions. As a framwork, we develop a simple descriptive growth model which allows for factor accumulation, technological diffusion and rate effects from human capital and which includes fixed regional effects...
